State Route 522 (SR 522) connects Seattle to its northeastern suburbs. Its southern origin is at Interstate 5 at the north end of the Roosevelt neighborhood in north Seattle, where it is a city arterial, Lake City Way N.E. Upon crossing the Seattle city limits into Lake Forest Park, its name changes to Bothell Way N.E. It continues through Kenmore and into Bothell, where part of it is designated Woodinville Drive. East of downtown Bothell, SR 522 becomes a freeway as the first segment of the Bothell-Monroe Highway. It continues through Woodinville to an at-grade intersection with Paradise Lake Road. From there, it continues east as a two-lane freeway into unincorporated Snohomish County to Monroe, where it ends at the junction with U.S. Route 2. It is about 25 miles (40 km) long in total.
Once called the Red Brick Road, SR 522 originally connected Downtown Seattle to the towns of Lake City, Lake Forest Park, Kenmore, Bothell, Redmond, Fall City and points east. From 1926 to 1930, U.S. Route 99 followed the present day SR 522 from Seattle to SR 527. Rebuilt and expanded after World War II, it remained a connector from downtown Seattle through to Redmond until the construction of Interstate 5, when its origination point moved several miles north along that freeway into the Roosevelt neighborhood of Seattle.
